Ecm Industries Llc 10-123 Butt Splice Connector 16-14 Awg 100 Pack

Product Description

The ECM INDUSTRIES LLC 10-123 is an insulated, solderless butt splice connector designed for making secure in-line wire terminations on 16 to 14 AWG conductors. Each connector uses a mechanical crimp method, eliminating the need for solder or open-flame tools on the job. The insulated barrel protects the connection from incidental contact and helps maintain circuit integrity in finished installations. This pack includes 100 connectors, making it practical for larger wiring runs or repeated service calls where consistent termination hardware is needed. Electricians, HVAC technicians, and low-voltage installers commonly use butt splices when extending, repairing, or splicing wire runs in control circuits, equipment wiring, and panel feeds.

The 10-123 connectors are suited for residential and light commercial electrical and HVAC wiring applications where 16 AWG or 14 AWG conductors are standard. Typical use cases include thermostat wire repairs, appliance wiring, motor lead extensions, and general control circuit splicing. The 100-count clam pack format supports both shop stock and field deployment, keeping a reliable supply on hand for service technicians who encounter wire splicing needs across multiple job types.

Key Features

• Insulated barrel for contact protection on completed splices
• Solderless crimp design — no torch or solder required
• Compatible with 16 to 14 AWG wire sizes
• 100-count pack reduces restocking frequency for active service techs
• Clam pack packaging keeps connectors organized and accessible

Compatibility

Designed for use with 16 AWG and 14 AWG copper conductors in standard electrical, HVAC control, and low-voltage wiring applications.

Installation Notes

Installation is performed by licensed electricians or qualified HVAC technicians following applicable NEC requirements. Always de-energize the circuit and confirm zero voltage with a meter before stripping or splicing any conductors. Use a proper ratcheting or calibrated crimp tool sized for the connector gauge to ensure a secure, gas-tight termination. Avoid over-stripping wire insulation, as excess exposed conductor inside the barrel can reduce connection reliability.
